3. INSTALLATION AND CONNECTION

3.1 Installation Illustration

Installation items:

The factory only provides the main unit and the water unit; the other items in the illustration

are user provided.

Attention:

Please follow these steps when using for the first time:

1. Open valve and charge with water.

2. Make sure that the pump and the water-inlet pipe have been filled with water.

3. Close the valve and start the unit.


3.2 Pool Heat Pump Location

The unit will perform well in any outdoor location provided that the following three factors are

present:

1.Fresh Air 2. Electricity 3. Pool filter piping/pumping

The unit may be installed virtually anywhere outdoors. For indoor pools please consult the

supplier. Unlike a gas heater, it has no draft or pilot light problems in a windy area.

DO NOT place the unit in an enclosed area with a limited air volume, where the units discharge

air will be re-circulated.

DO NOT place the unit near shrubs or other obstacles, which can block air inlet.

3.3 How Close To Your Pool?

Normally, the pool heat pump is installed within 25 feet of the pool. The greater the distance

between the pool and the heater, the greater the heat loss from the plumbing. The plumbing is

often buried. Therefore, the heat loss is minimal for runs of up to 50 feet (50 feet to and from

the pump = 100 feet total), unless the ground is wet or the water table is high. A very rough

estimate of heat loss per 100 feet is 0.6kW-hour, (2000BTU) for every 5F difference in

temperature between the pool water and the ground surrounding the pipe, which translates to

about 3% to 5% increase in run time.


3.4 Swimming Pool Heat Pump Plumbing

The Swimming Pool Heat Pumps exclusive rated flow titanium heat exchanger requires no

special plumbing arrangements except a bypass (please set the flow rate according to the

nameplate). The water pressure drop is less than 1.45 Psi at max flow rate. Since there is no

flame or other high temperatures source, the unit does not need metal plumbing. The PVC

pipe can be run straight into the unit.

Location in plumbing loop: Connect the unit in the pool pump discharge (return) line

downstream of all filter and pool pumps, and upstream of any chlorinators, ozonators or

chemical pumps. (See illustration)

Standard models have slip glue fittings which accept 1.5” or 50mm PVC pipe for connection to

the pool or spa filtration plumbing. By using a 1.5” to 1.5” you can plumb 1.5” PVC pipe.

Give serious consideration to adding a 1.5” PVC sch 40 union (Lowes item #188234) at the unit

inlet and outlet to allow easy draining of unit for winterizing and to provide easier access

should servicing be required.

Condensation: Since the heat pump cools down the air about 4-5F, water may condense on

the fins of the horseshoe shaped evaporator. If the relative humidity is very high, this could be

as much as several liters an hour. The water will run down the fins into the base pan and drain

out through the barbed plastic condensation drain fittings on the side of the base pan. This

fitting is designed to accept ¾” clear vinyl tubing which can be pushed on by hand and run to a

suitable drain. It is easy to mistake the condensation for a water leak inside the unit.

NOTE: A quick way to verify that the water is condensation is to shut off the unit and keep the

pool pump running. If the water stops running out of the base pan, it is condensation.

AN EVEN QUICKER WAY, IS TO TEST THE DRAIN WATER FOR CHLORINE - if there is no chlorine

present the water is condensation.


3.5 Swimming Pool Heat Pumps Electrical Wiring NOTE: Although the units heat exchanger is electrically isolated from the rest of the unit, grounding and bonding the unit is still required to protect you against short circuits inside the unit. The unit has a separate molded-in junction box with a standard electrical conduit nipple already in place. Just remove the screws and the front panel, feed your supply lines in through the conduit nipple and connect them to the three conductors already in the junction box (four connections if three phase). The Heat Pump should be connected by electrical conduit, UF cable or other suitable means as specified (as permitted by local electrical authorities) to a dedicated AC power supply branch circuit equipped with the proper circuit breaker, disconnect or time delay fuse protection. When configured for solar usage, the heat pump must be connected to a dedicated breaker in the SPP-supplied Power Manager. See separate instructions for installing and connecting the solar panels. Disconnect - A disconnect means (circuit breaker, fused or un-fused switch) should be located within sight of and readily accessible from the unit. This is common practice on commercial and residential air conditioners and heat pumps. It prevents remotely-energizing unattended equipment and permits turning off power at the unit while the unit is being serviced. Follow the required standards of the AHJ. When using the SPP solar Power Manager the disconnect is included. 3.6 Initial startup of the unit NOTE-In order for the unit to heat the pool or spa, the filter pump must be running to circulate water through the heat exchanger. Startup Procedure - After installation is completed:

1. Turn on your filter pump. Check for water leaks and verify flow to and from the pool. 2. Turn on the electrical power supply to the unit, and then press the key ON/OFF of

controller. It should start in few seconds. 3. After running a few minutes, make sure the air leaving the top (side) of the unit is

cooler. (Between 5-10F) 4. With the unit operating turn the filter pump off. The unit should also turn off

automatically. 5. Allow the unit and pool pump to run 24 hours a day until desired pool water

temperature is reached. When the water-in temperature reaches the setting, the unit shuts off. The unit will now automatically restart (as long as your pool pump is running)

when the pool temperature drops more than 2F below set temperature.

Note: Time Delay - The unit is equipped with a 3 minute built-in solid state restart delay included to protect control circuit components and to eliminate restart cycling and contactor chatter. This time delay will automatically restart the unit approximately 3 minutes after each control circuit interruption. Even a brief power interruption will activate the solid state 3 minute restart delay and prevent the unit from starting until the 3 minute countdown is completed. Power interruptions during the delay period will have no effect on the 3 minute countdown. 4. USAGE AND OPERATION 4.1 Function of controller

5.1 Maintenance

Check the water supply often. You should avoid the condition of “no water” or air entering into system, as this will affect the unit’s performance and reliability. You should clear the pool/spa filter regularly to avoid damage to the unit as a result of the dirty or clogged filter.

The area around the unit should be dry, clean and well ventilated. Clean the side heating exchanger regularly to conserve efficiency.

The refrigeration system should only be serviced by a certified technician.

Check the power supply and cable connection often. Should the unit begin to operate abnormally, you should switch it off and contact a qualified technician for service.

Drain all water from the water pump and plumbing system, so that freezing of the water in the pump or system does not occur. You should drain the water at the bottom of water pump if the unit will not be used for an extended period of time. You should check the unit thoroughly and fill the system with water fully before using it for the first time after a service or repair.
